Plastic Ductile Damage Evolution And Collapse Of
Plates And Shells

Abstract
This paper deals with modelling and simulation of plastic ductile damage
evolution in thin-walled structures and its effect on the load-carrying behaviour
in the geometrically and physically non-linear range of deformation. In this
context, gradual stiffness degradation, damage evolution, local failure initiation,
and final collapse of the structure are problems of primary interest. The approach
adopted accounts for elastic-plastic material behaviour, isotropic as well as
kinematic hardening, material damage, finite displacements and finite rotations.
Finite element simulations illustrate the effect of material damage on the load
carrying behaviour of thin-walled structures.
